HEELBBURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent N'o. 372,612, dated November l, 1887.

Application filed March 12, 1887. Serial No. 230,583.

To all whom it may concern,.-

Be it known that I, ALFRED B. FowLnR, a citizen of the United States, and a resident of Exeter, in the county of Rockingham and State of New Hampshire, have invented new and useful Improvements in Heel-Burnishing Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in heel-burnishing machines, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a rear elevation of the machine. Fig. 2 represents a central vertical section of the same. Fig. 3 represents an enlarged Vertical section on the line A B, shown in Fig. 2. Fig. 4 represents a verticalsection on the line G D, shown in Fig. 2. Fig. 5 represents an enlarged cross-section on the line X Y, also shown in Fig. 2; and Fig. 6 represents a side elevation of the heart-shaped cam for imparting an oscillating motion to the burnisher-shaft.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

a is the frame or standard of the machine, having bearings a a for the rotary driving shaft b. (Shown in Figs. l and 2.)

b b are respectively fast and loose pulleys on the drivingshaft b, as usual. By means of belt-power applied to the pulley b a rotary motion is imparted to shaft I).

b3 and b* are pulleys, also secured to shaft b, the former for setting in motion the mechanism by which an oscillating-motion is given to the burnishing-shaft and the latter for actuating the mechanism by which a longitudinal reciprocating motion is imparted to the said burnishing-shaft, as will hereinafter be described.

To the top of frame a is secured the bearing c for the rock-shaft c, said shaft being further supported in its rear end in the forked bearing-bracket d, secured to the rear of frame a, as shown in Figs. 1, 2, and 3.

eis the burnishingshaft, journaled in the respective bearingsf and g, and having its rear end pivoted at lc to the bracket or lever K, as shown in Fig. 2. rlhe bearing f is free to move up and down in the forked arm F, secured to the (No model.)

rock-shaft c in front of bearing c', as shown in Figs. 2 and 4, the said bearing f being provided with guide-pinsff, projecting through slots F F in the sides of the forked arm F, so as to keep the said bearing and forked arm connected together during the various motions of the burnishing-shaft.

F is a cap-plate secured to upper end of the forked arm F, and through such cap-plate is screwed the adjustable screw F3, on which is held, between nuts or collars F4 F, the upper end of the flat spring F5, the lower free end of which presses on top of the bearing f, so as to cause the burnisher-tool E, secured to the forward end of shaft e, to exert a proper pressure on the heel of the boot or shoe S that is being burnished. During the operation of burnishing the boot or shoe heel the boot may be secured to a suitable jack, as is common in machines of this kind, or it may be held by hand, as may be desired.

The bearing g is free to move up and down in the forked arm G, secured to rock-shaft o, back of the bearing o, as shown in Figs. 2 and 5, the said bearing g being provided with guide-pins g' g', projecting through slots G G in the sides of the forked arm G, so as to'keep said bearing and forked arm connected together during the motions of the burnisher- Shaft.

The mechanism for imparting an oscillating motion to the burnisher-shaft is carried out as follows: To the interior of the hollow standard a is secured the bearing h, in which is journaled the worm-shaft H, to which is secured the worm H. (Shown in Figs. 2 and 4.) 71, is a pulley secured to the worm-shaft H, and by means of a belt, h, a rotary motion is conveyed to the pulley 7L from the small pulley b3 on the rotary drivingshaft b. The worm H meshes into the teeth of the worm-wheel L, having shaft or spindle Z,journaled in the bearing L', secured in a suitable manner within the standard a, as shown in Fig. 2. To the face of the worm-wheel L is secured, in a suitable manner, theheartshaped cam M. (Shown in Figs. 2 and 6, as well as in dotted lines in Fig. 4.) As the cam M rotates with the wormwheel L, it actuates a pair of pins or projections, o o, on the side of the toothed rack O, and thus causes the latter to reciprocate. The rack O has a downwardly-projecting guide- IOO piece, 0.', passing freely into the slot p in the bracket or bearing-piece 1?,.secured in a suitable manner to the inside of the hollow standard a, as shown in Figs. 2 and 4, by which arrangement the rack O is properly guided during its reciprocating motion. A set-screw, p', and washer or plate p, secured to the lower end of guide-piece O', prevents the rack O from moving out of its bearing-piece O', as shown in said Figs. 2 and 4. The teeth of the rack O engage in segmental teeth q in the lower end of the rock-lever Q, that is pivoted on the stationary fulcrum-pin g, secured to frame a., as shown in Figs. 2 and 4, said lever d Q passing through a slot, a, in the top of frame a, and has in its upper end segmental teeth q,

' meshing into the toothed segment F in the lower portion of the forked arm or lever F, as shown in Figs. l, 2, and 4. Thus it will be seen that by this mechanism .an oscillating motion is imparted to the burnisher-tool E, to

cause it to follow the curvature of the heel yfrom rear to front, the spring F5 during such motion of the tool E causing it to follow the irregularities in the heel curvatures and to bear against the heel with a proper yielding pressure.

For the purpose of impartingalongitudinal reciprocating motion to the burnisher-shaft `from-the rotary driving-shaft b, I use the following intermediate connecting mechanism: From the pulley b4 on the driving-shaft b leads a belt, b5, to the pulley r, secured to the shaft It, which latter is supported in bearings R R', secured to frame a, and to said shaft R is keyed or otherwise secured the eccentric disk R, that is surrounded by the ring R3, and to the latter is secured, preferably in an adjustable manner, the rod R, the upper end ofl 3, said hub casurrounding the rock-shaft c and preferably splined upon it, so that said hub k3 of the lever K may be free to slide forward and back on shaft c and still partake of the rocking motion of the latter andthereby cause the burnishershaft e to reciprocate longitudinally and thus to impart a forward-and-back reciprocating motion to the tool E, so as to :reach all parts of the heel, from top to bottom of the latter, during the operation of the machine.

For the purpose of regulating and adjusting the longitudinal reci procation ofthe burnishershaft e, I use the following mechanism, viz: I make in the lever T a slot', T, in which is adj ustable the bearing T3. (Shown in Figs. 2 and 3.) I also make slots cl d in the forked sides of the bracket d, and in said slots are adj usta` ble the bearings cl d. (Shown in Fig. 3.) Midenlargement, t, the ends of which bear against the inner flanged ends of the bearings d d. The ends of the bolt t are scre`w-threaded and provided with hand-nuts t3 t5, and between such hand-nuts and the outside of the forked bracket d d, I locate upon the bolt t a pair of hubs or washers, t* t4, (shown in Fig. 3;) and it will thus be seen that by loosening the handnuts t3 t3 the bolt t is released from the bracket d d, and it may now be adjusted up or down with its bearings in the slots in said bracket and lever T, according to the amount of`reciproeation desired on the burnishing-tool to compensate for height of heel on the boot or shoe, and after being so adjusted the bolt tis secured rmly to the slotted bracket d d by simply tightening the hand'nuts t3 t3.

E is a gas-pipe connected to the tool E for heating it, as is usual in machines of this kind; but any other or well-known means for heating the burnishing-tool may be used to equal ading-shaft to cause the tool to reach all parts from the top to bottom of the heel, an oscillating motion to cause the tool to follow the curvatures of the heel from front to rear, and an in-and-out yielding motion t0 cause the tool to bear properly against the curved portions of the heel while the said tool is oscillated and longitudinally reciprocated.

Having thus fully described the nature,con struction, and operation of my invention, I wish to secure by Letters Patentk and claiml. In a burnishingmachine, the herein-de` scribed mechanism for imparting an oscillating motion to the burnisher-shaft, consisting of the rotary driving-shaft b, having pulley b3, the belt h, leading from it to the pulley h on the worm-shaft H, the worm H, engaging with the worm-wheel L, the cam M, secured to said worm-wheel, the rack O, reciprocated by the said cam and having teeth engaging in the teeth in the lever Q, said lever being supported to rock on the fulcrum qand having teeth in its upper end` engaging in the teeth in the lower end of the forked arm F, the latter Vbeing supported on the rock-shaft c and provided with an outandin movable bearing, f, for the burnisher-shaft, all combined and operating substantially as set forth.
